Answer:
When glucose is scarce, glycogen phosphorylase, the enzyme catalyzing the breakdown of glycogen, is activated by the "Phosphorylation" of a particular serine residue.
Explanation:
Phosphorylation is a biochemical process and it has the addition of the phosphate with an organic compound. Production of the glucose monophosphate as a result of attachment of phosphate with glucose. Attachment of phosphate to the adenosine diphosphate which leads to the formation of the adenosine triphosphate. So, we can conclude that phosphorylation is a process of the addition of a phosphoryl group. Basically phosphorylation happens to release a phosphate group in an organic molecule.
